STEREOTYPING AND TYPE-METAL-FOUNDING AP A g- Specification of Letters Patent.

' Application filed December 8, 1906, Serial No. 846,946.

. hereby declare that the ollowing is a full,

'ence be clear, and exact description thereof, referin s, whic form part of this specification.

his invention is an improvement in stereotylping and type-metal founding apparatus, an relates particularly to the means for delivering the hot metal from the melting pot tothe molds.

The object of the invention is to provide themetal pump with a discharge spout having an adjustableor turnable nozzle that can be swung back" into the pot and heated by the molten metal therein before the casting operations begin, and which, between casting operations, can be turned back into the melting pot so as to be kept hot and in condition for instant use.

In the present known ap aratus the pump s outs or nozzles chill t e metal passing t erethrough, and thus retard or stop the castin operation by the accumulation of chille metal on the walls of the spout; by my present invention the metal cannot chill 1n the spout or nozzle, inasmuch as the latter can be'thoroughly heated to the temperature of the molten metal before it is brought to o erative position and the metal started t ough it.

In my invention, when the nozzle is thrown into discharging position, it is ready for operation and no dripping from the nozzle Wlll occur after the pump piston has finished its stroke, because the nozzle is so thoroughly heated that no metal is chilled therein; while in the ordinary devices the metal drips be cause the nozzle is not heated enough to keep the metal lively and consequently much metal will chill therein.

It has been frequently necessary in the old ap aratus to heat the nozzle by gas jets in or er to remove the chilled metal and this of course retards the o erations, and causes great annoyance and oss of time, sometimes when time is of the utmost importance.

In my device if the nozzle should be left in discharging position until chilled, it can be quickly heated by turning it over into the had to the accompanying draw- \ments of the nozzle;

of the melting pot with pump and nozzle embodying my 1m rovements. Fig. 2 is a sectional view on me 22, Fig. 1. Fig. 3 is a section on line 3-3, Fig. 1. Fig. 4 is a detail section on line 44, Fi 2.

The melting pot 1 may be of any desired construction. Within this pot is a submerged metal-pump comprising a cylinder 2 suspended from a bracket 2 attached to the side of the pot, and closed at its upper end but open at bottom. The cylinder piston 2 is connected to arod 2, extending through the up er end of the pump and connected by linli 2 to the inner end of the um -operating lever 2, pivoted at 2 on a brac et 2 at tached to the side of the pot as shown.

The pump has, an outlet 2 in its upper end, communicating with the discharge pipe which is composed of an elbow portion 3, fixedly attached to the top of pump, and a nozzle portion 3 rotatably connected to the upper end of part 3 as, shown,so that the nozzle 3 can e swung into either position shown in Figs. 1 or 2. A convenient mode of connecting the nozzle and elbow is to have the upper end of the elbow 3 externally threaded as at 3 and to form the nozzle with a right angled bend 3 at its base, and with an internally threaded flange 3 on its inner end, and screw the flange onto the elbow 3 as shown-thus allowing the nozzle to be swung upon the elbow as a pivot, and at the same time always maintaining a close joint therebetween,and this construction prevents lateral wabbling or unsteady move- As customary, the pot 1 is to be kept filled with molten metal, to about the level indicated in the. drawings, and before the casting operations are begun the nozzle should be turned into the position shown in full lines in Fig. 2, so that it lies upon and is artly submerged in the molten metal, andt us becomes heated to the temerature of the metal. Then when the castmg operation is to be performed tbe nozzle is turned to the position shown in full lines in Patented May 14, 1907.

Fig. 1, and the molten metal forced therethrough by operating the pump piston, as usual. After the casting operations are over, or in the intervals between such operations, the nozzle can be turned back into the pot as shown in Fig. 2 and kept hot until another casting operation is to be performed. If the nozzle should be left in the delivering position until cold: or if for any reason some of the metal should chill therein at any time, it can be quickly cleared by turning it back into the molten metal as shown in Fig. 2, until it is reheated.

The advantages, utility and simplicity of this invention will be readily appreciated by those skilled in the art.

Having described my invention what I claim as new and desire to secure by Letters Patent is: 1. In combination, a melting-pot, a metal pump therein, and a discharge nozzle connected with the pump, and adapted to be turned into the hot metal in the pot to be heated thereby, substantially as described.

2. In combination, a metal melting-pot, a metal pump therein,- and a discharge pipe, comprising a section fixedly attached to the outlet of the pump, and a nozzle section connected to the fixed section and adapted to be turned into the hot metal in the pot to be heated, or over the edge of the pot to dis charge the metal.

3. In. a stereotype casting apparatus, the combination of a metal melting-pot, a metal pump therein, and a discharge pip-e, comprising a section attached to the outlet of the pump, and a nozzle section rotutably con nected to the first section and adapted to be turned into the hot metal in the pot or over the edge of the pot, substantially as de" scribed.

4. In a casting apparatus, the combination of a melting pot, a metal pump suspended therein, a pipe elbow connected to the outlei of the pump at one end and haying its other end threaded, a nozzle having its inner end threaded to engage the threaded end oi" the elbow whereby said nozzle can be turned either into the metal in the pot to be healed.

or outwardly to project over the edge of the pot, substantially described.

5. In stereotype I- ting a'g'iparatus, the combination of a meltm -poi', a metal pump suspended therein, a pipe elbow connected to the outlet of the pump at one end and having its other end threaded, and a nozzle having a bend on its inner end provided with an internally threaded flange screwed onto the threaded end of the elbow whereby said nozzle can be turned'either into the metal in the pot to be heated. or outwardly over the edge of the pot to deliver the metal, suhstun tially as described.

in testimony that I claim the foregoing us my own, l afiix in sigi'iaturc in presence of two witnesses. V V
